Patented Feb. 10, 1914.

Application filed December 14, 1912. Serial No. 736,739.

To all ur/mm. it may rxomrern.

lle it known that. I, NTCHOLAS Aot'isaxo, a subjectv of the King of Italy, and residing in the city of Newark, county of Essex, and State of Newjlersey. have invented certain new and useful Improvements in Clippers, of which the following is a specification.

ln clippers of the type to which my invention amiertains, a multiple toothed stationary blade is provided over which the multiple toothed reci 'irocating blade is o ')erated. the multiple teeth of the two blades serving as a shearing device for shearing the. hair from the head of a person or the body of an animal. the hair passing between the multiple teeth in somewhat. the same manner as it does l'ictween the teeth of a comb. This operation, however, is well known. In using this device where it. is desired to grade the. clipping. that is, to cut the hair close to the skin at one. point and grade the cutting tlu-reof. to gradually lengthen it at others it. is necessary to tilt the handles of the clipper using the heel of the stationary blade as a sort of a fulcrum to bear upon the skin of the. subject. This often produces uneven cutting and results in the ragged t'tp[)0t1l2lntf0 of the hair after the operation is completed.

The object. of my invention is to provide a clipper with power o 'ierating mechanism for reoiprocating the movable blade and provide the stationary blade with a pivoted comb on its under side and utilize the mo\ able handle f the clipper for oscillating the pivot comb toward and away from the under side of the stationary blade. The points of the teeth of the comb in operation bear upon the skin or scalp of the subject.

and as the comb is oscillated away from the stationary blade it serves to elevate the ensubject. l also provide upon the handles f the device a scale by which the degree of oscillation of the comb may be readily observed, this and other improvements in the clipper forms the subject. matter of my inveution.

In the accompanying drawings which form part of the specification: Figure 1 illustrates a plan view of my improved clipper with the incloslng cap or cover removed to show the interior mechanism. Fig. 2 is a side elevation partly in Section of the clip per. Fig. a plan view of the. stationary blade. Fig. 4 is a plan view of the comb.

Fig. 0 IS a side elevation of the comb. Fig.

6 is a side elevation of the cap or cover and Fig. 7 is a plan view of the same. Fig. 8 illustra es. a slight modification of the driving mechanism for operating the reciprocating blade.

Similar reference numerals refer to like parts throughout the specification and drawings.

The clipper consists essentially of a spring barrel 1. having integrally connected therewith the handle 2 and a forwardly extending step 3. The so-called stationary blade 4 is secured to the step 3 by means of two screws .7. This stationary blade is provided with the. plurality of cutting teeth 6, at its forward rdgep Two upwardly extending posts 7 are rigidly secured to the upper side of the stationary blade t. which serve as guides for the reciprocating blade 8. The latter blade provided with the plurality ot' cutting teeth 9 usually two or three fewer in number than time upon the stationary blade. 4. Th sl ts 10 are provided in the rm-iprocating blade which take over the posts 7 above referred to. The reciprocating blade 8 is also provided with the oval slot ll. in its center for a purpose hereinafter to be described. The step 3 is pro vided with an upwardly extending screw threaded post 12 which serves the double 1 purpose of forming a pivot for the handle l3, and also fastening means of the cover or cap 14. lhis cap is of the general shape and contour as illustrated in Fig. 7 and is provided with an aperture 15 Which takes over the threaded post 12 and is secured to said post by means of the thumb nut 16. The rear end of the on p bearing rests upon the spring barrel. 1 as shown while the for ward edge rests upon the upwardly extending posts 7. Small dowel holes are provided tire clipper from the skin or scalp of the 111 said posts 7 to receive the dowel points .17 in the lower side of the cap, so that when in position the thumb nut 16 rigidly secures the cap in position. The rear corners of the stationary blade 4 are notched out as at 18 and in the para lel faces of such notched out portions, I provide the screw holes 19. lVithin the spring barrel 1 is a coil spring 20, one end of which bears upon the adjust ing screw cup 21, and the opposite end bears upon a spring cap 22, the outer face of which is provided with a conical cavity 23. The cap 22 is held from escape by means of the ledge extending around the cavity of the spring barrel 1. The pivot handle 31 as above described is pivotally mounted upon close to the skin of the subject as possible.

the post 12, underneath the cap or cover 14,

which serves to retain it in position. This handle is provided with a small ball pointed pin which bears in the conical cavity 23. It will be seen that when the handle 13 is gripped in the hand with the handle 2, the spring 20 serves to yieldingly resist any pressure upon the handle. Projecting laterally from the side of the handle 13, is an arm 24, which normally lies parallel to the side of the spring barrel, said spring barrel serving as a stop for said arm to prevent the spring within the barrel from opening the handle too wide.

Upon the parallel faces of the notched rear portion 18 of the stationary blade 4 are pivoted two upwardly extending pivot lugs of the comb 26, said comb normally lying flat against the lower side of the stationary blade, but capable of swinging upon the pivot screws 25; which latter are screwed into the apertures 19. The left hand pivot lug 25 is provided with an upwardly extending supplemental lug 27, which is located just forward of and in position of engagement with the extremity of the arm 25, so that as the arm 24 is moved forwardly by the operation'of the handle 13, the comb may be oscillated upon its pivots. Secured to the center of the rear edge of the comb is a flat spring 28, the free end of which bears upon the lower side of the spring barrel 1 and serves to yieldingly hold the said comb flat against the under side Of the stationary blade. r

In the cap or cover 14 is the journal bearing 29, in which is located the short section of shaft 30, upon the inner end of which is located an eccentric cam 31., the latter when in position being located in the slot 11 in the reciprocating blade. The outer end of the shaft is rigidly secured to a flexible shaft 352 leading from some motor, preferably an electric motor. It will be readily seen that the rotation of the flexible shaft will rotate the short shaft in its bearing and with it the eccentric cam, resulting in the rapid reciprocation of the blade 10. When the handle l3 is moved upon the pivoting post 12, the arm 24 will oscillate the comb away from the blade 4. l t the points of the teeth of the comb bear upon the skin or scalp of the. subject the result will. be the elevation of the stationary blade 4'; in fact the whole device will be carried away from the skin or scalp of the subject. The points of the teeth 26' of the comb are curved and normally located in the slots between the teeth of the stationary blade, so that the points of the teeth in the stationarv blade may be operated as Ordinarily the points of the. teeth of the stationary blade are chamfered upwardly as shown in Fig. 2, as this permits the points subject and .thus clip' the hair much more closely than otherwise could be done if the teeth were chamfered or wardly.

Projecting rearwardly from the spring barrel and extending in the arc of the circle of which the post 12 is the center is a flat scale 33, and upon the handle 13 is located an arm 34, at the outer extremity of which is a pointer 35, in position of register with the divisions upon the scale. The scale and pointer serves as an index to the degree of oscillation of the comb.

I/Vhile I have shown a specific means of oscillating the comb from the pivot handle 13. I do not desire to confine myself to that only, as any means for oscillating the comb would come within the spirit and scope of my invention.

In Fig. 8 I have illustrated a slight modilcation of the means for reciprocating the blade 8. In this case the cam slot 36 is provided with the are shaped ends 37. On the lower end of the short section of theshatt 30, I provide a cam arni 38 which projects into the slot 32 for engagement with the cams It will be readily seen that the rotation of the shaft 30 with the cam arm 34, will result in rapid intermittent reciprocation of the blade 8, and that during the period when the end of the cam arm 34 is not in contact with the earns 33, the blade 8 will be substantially at rest in either one of its extreme positions. Those periods of rest are quite essential to the proper operation of the clipper, for the reason that if the shaft 30 is rotated at a high rate of speed, the form of the eccentric cam illustrated in Fig. 1, will leave no short periods of rest. for

the blade 8. with the result that the hair of the subject will have no time to be arranged properly between the teeth of the stationary blade 4. Ordinarily, however, the shaft- 30 docs n t. rcvolvc at the speed which will preclude. the ec entric rain 31 from actuating the blade 8 to effectually clip'the hair of the subject. ()thcr incans may, be provided for applying power to reciprocate the blade 8 and I do not limit myself in this respect to any specific means for operating said blade 8.
